My 2019 grand scenic iconic petrol 1.3 started showing check anti pollution system light after using this product and give the car a good drive the light went off. The car performance is great. I recommend this. Review: Erased cat and O2 sensor faults - Incredible result. Poored a bottle on a full tank and 50 miles later my obd scanner found 0 issues. Before had catalyst and o2 sensor faults + engine light. To be honest i 1st used on a full tank the wynns blue bottle, seen a bit of better response on the throttle but errors didnt go away. Second refill with the black bottle sorted out everything. ## Features - Causes serious eye irritation. - Causes skin irritation. - Flammable liquid and vapour. - Harmful if inhaled. - May be fatal if swallowed and enters airways. - May cause damage to organs through prolonged or repeated exposure. - May cause respiratory irritation. - Suspected of causing genetic defects. - Removes deposits (oil and unburnt fuel particles) and reduces emissions - Extends the life of the catalytic converter and oxygen sensors - Prevents the OBD warning light from illuminating ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B018E214KA | | Best Sellers Rank | 4,051 in Automotive ( See Top 100 in Automotive ) 2 in Air Flow Sensor Cleaners | | Brand | Wynn's | | Customer Reviews | 4.1 4.1 out of 5 stars (345) | | Date First Available | 27 Dec. 2015 | | Delivery information | We cannot deliver certain products outside mainland UK ( Details ).
